SPECIFICATION formin part of Letters Patent No. 498,662, dated May 30, 1893.

Application filed December 21, 1892. Serial No. 455,921. (No model.)

'To all whom it may conc'ern;-

Be it known that I, JOHN ALVY KNIGHT, a

, citizen of the United States, residing at Saltil loville, in the county of Washington and State tion.

of Indiana, have invented a newand useful Machine for Stroppingand Honing Razors, of which the following is a specification.

' My invention has for its object the provision of a machine adapted to be operated by" hand or foot-power, and to strop-or hone razors; and to accomplish the same in an efficient, uniform, and convenient manner.

WVith these'objects in view the i'nvention consists in certain features of construction hereinafter specified and particularly pointed out in the claims- Referring'to the drawings:Figure ,1 is a perspective View of a machine embodying my invention. Fig. 2 is a vertical transverse sectional view thereof.

Fig. 4: is a top plan view. Fig. 5 is a longitudinal sectional view of the hone adapted for use in connection with my machine.

- Like numerals of reference indicate like parts in all the figures of the drawings.

Upon a suitable base or foot 1 there is pivoted by a bolt 2 a standard 3, which by means of the character of its fastening is capable of a slight swinging movement upon said base of the. standard 3. The shaft 6 isprovided at its upper end'with an eye 7, and in the same is located a hook-bolt 8 upon which above Below the the eye is mounted a thumb-nut 9. v hook-bolt there projects from the face of the shaft 6 a book 10.

.11 designates a strop one end of which is hooked in the hook-bolt 7, and the other or lower end of which is engaged by the lower hook 10. It will be obvious that this strop may be regulated as regards its tension, through the medium of thethumb-nut upon the hookbolt, that is, by running the thumb-nut down Fig. 3 is a front eleva-- upon the hook-bolt, the-same binding against the eye 7, the hook-bolt Will be drawn up and the tension of the strop increased, or on the other hand by running the nut upwardly upon the hook-bolt the strop will be loosened.

.In a bearing-block 12 locatedupon the rear side of the foot or base 1 thereis'pivoted'upon a transverse pin 13, the lower end of,a resilient bar 14, that extends above the standard 1, and at its upper end carries a U-shaped,.

forwardly-disposed bearing-yoke 15, in which r is mounted for rotation a grooved pulley 16.

The resilient-bar 14, is provided between its ends, and in this instance near tits lower end,

with a perforation 17, and through it extends r a bolt 18, whose forward end issecured to the I standard 3 and whose opposite ,or threaded I end beyond the perforation 17 isprovided with anut 19. By adjusting this nut upon the bolt 18, the pressure of the grooved pulley against the rear side of the shaft 6 upon Which it bears obvious. v I r 'A transverse bearing-block 2 1, is secured may be regulated, as will be rigidly to the face of the standard 3, and is provided upon its upper sidewith ahalfbearing 22, in which is mounted the central portion of a shaft 24, whose ends beyond the bearing block are provided with cranks 25 and 26, the crank 25 being provided with a handle by which it may be manually operated; and the inner crank 26 being loosely connected to the upper end of the sliding bar 27. Above the bearing-block 21, a companion bearing-block 21 is located, the same being made adjustable upon the lower block by means of a set-screw 21? passed through a lug 21 that projects from the face of the stand ard 3. I

Across-bar 29 is secured upon the upper end of the standard 3, and is provided at its ends with a pair of forwardly-disposed bearing-arms 30, which arms are provided near their front ends with hearing openings 31, in-

, which is journaled a rock-shaft 32. This 'rockshaft-has fixed upon it between its ends a v circular head 33, and the sameis provided with a radial recess 34:, at the sides of which hooks 35, are located.

Ashort vertical shaft 36, is journaled on the rear end of the outer bearing-arm 30, and

' a bearing48, for the lower end'of a rod49.

movement of said shaft 6.

the same is provided with a ratchet-wheel 37. Coiled upon this shaft 36 'isa spring 38, one end of which is made fast to the shaft and the coil terminates at one side of the ratchetwheel. This terminal of the coil is connected by a curved lever 39, passing under the crossbar 28, with a pin 40, eccentrically located upon the circular head This shaft 36 may be rotated to tighten or loosen the coil thereon, and may be locked at any point of its adjustment through the medium of a pawl 41, pivotally mounted upon the outer bearing-arm 30.

. Pivoted upon a bolt 42 to the front face of the standard 3 immediately above the bolt 2, is a rocking-block 43; and projecting from the standard 3 to one side of the pivot 42 of said block is a lug 44 in which a set-screw 45 is threaded, and has its lower end bearing upon the end of the aforesaid rocking-block. The opposite end of the rocking-block is slotted, as indicated at 46 in a longitudinal manner, and secured upon the upper side of the block in rear of the slot or beyond its inner end is the terminal of a coiled-sprin g 47, the remaining terminal of said spring extending sidewise and over and above the slot46, forming A keeper 50, extends over the bearing terminal of the spring, limiting its upward movement, while it will be obvious that the said bearing and its bar 49 may be depressed into the aforesaid slot 46, all for a purpose hereinafter apparent. The bar 49 is provided near its upper end with a longitudinal slot 51, and through this passes the inner crank 26 of the operating shaft, and beyond it said crank is provided: with a nut. The upper endof the bar49 is provided with a transverse leathercovered, or otherwise formed, friction-head 53, and the same is located immediately below or in line with the circular head 33.

A wire bail 54, has its terminals secured to the opposite sides of the standard 3, from which it projects and loosely embraces the shaft 6, and said bail is provided near its inner side or end with an upwardly-disposed kink 55, and a ring 56 is mounted for sliding loosely on the bail, and is designed to take intosaid kink. The bail is pivoted, and from the ring 56 thereof. to a pin 57, extending from the face of the circular head 33, there is a wire 58. A pin 59 projects from the face of the shaft 6, and is designed to strike the bail anddepress the same upon each downward An-arm 60 projects from the upper endof the shaft 6 and terminates at its outer end in an eye 61. A wirerod 62 extends from the cross-bar 29 through the eye 61 and above the same is provided with acoil 63 having an extremity or terminal 64. To this extremitythere is secured a wire rod 65, which passes through the eye 61 and is connected by a pin 66 to that the machine is adapted for honing as the circular head 33 at a point diametrically opposite that at which the wire rod 58 is connected'.

B the blade, and O the shank thereof.

This completes the construction of the device as adapted for str'opping razors, andI will now proceed to describe the operation thereof. A designates the handle of a razor, The hooks at the side of the circular head having been swung upward, the'shank of the razor is slid, back-edge first, into the recess 34 of said head, after which the hooks are swung forward, and being ofspring-metal snugly clasp or..bind the razor in the head. The

cated reciprocates the pitman 27, thus raising and lowering, or in other words, reciprocating upon the ways 4 the head 5 which carries the shaft6 that supports the strop 11. In this manner the strop' is given a reciprocatory motion, and is yiel'di'ngly pressed to the front by means of the resilient bar 14, so that it is forced toward therazor. The rotation of the crank-shaft serves to vibratethe rod 49 and thef-riet-ion-shoe 53 is brought into contact with the under side of the circular head at each back and forth movement, thus serving to partially rotate said circular head at each movement, and said head carrying the razor the latter is reversed or turned, the mechanism being so timed with relation to the reciprocating shaft 6 that the turningoccurs just previous to the complete ascent orv descent of said" shaft 6. It will be, seen that the spring mounting of theftod 49 will permit 'the same to yield vertically and pass by the circular head,while at the same time sufficient frictional contact between the twoobjects is maintained. The circular head in its oscillations is governed by the two wires 58 and 65., one of which it, will be seen extends up and the other downandare connected at diametrically opposite sides of theaforesaid circular head. By tightening and loosening the spring on the shaft36 it will be scent-hat the pressure of the razor-edge on the strop may be regulated, and also that said spring serves the purpose of turning the razor after the friction-shoe, which strikes the circular 1 heads, leaves the same,the spring completing the movement and bringing the razor-edge IIO against the strop or hone, and the wires 58' and 65 check the fall or limit the oscillatory movement of the razor so that the same is lowered flat against thestrop or hone, and no round edges can be formed It will beseen that by reason of the loose connectionbetween tionary or vertical, and thus we are enabled to move the razor across the strop so that a uniform sharpening takes place.

As best shown in Fig. 5' it will be, seen .the strop-carrying mechanism remainsstahas seated therein the-hone, which preferably I consists of thefstone or Ihone proper 7 1, and

a backing ofwood. Thehone is not as long:

as the frame in which-it is seated, so thatrecessesare formed between the ends of the I hone and the frame, and in said recesses are located pads 72, which constitute a softsu'rface upon which the razor-back may be turned at theend ofeach stroke, thus avoiding injury and marring of said edge. The

. frame, it will be seen, is secured to the shaft adapted to skillfully and efficiently strop or accomplishing the result in a more andexpeditious manner.

Having described my invention, what I 6, and the operationjof honing is precisely the same asthat of stropping. I I I I From the foregoingdescription in connec= tion with the accompanying drawings, it will be seen that I have provided a machine thatmay becheaplyconstructed and readily operated by experienced persons, andwhich is hone razors, thus reducing the labor usually necessary for carrying on this operation and efficient claim is I 1.
